DOUBLE-LEGGED COUPLING-PIN FOR VEHlCLE-SHAFTS.-

SPECIFICATION forming part of Letters Patent No. 766,412, dated August 2, 1904. Application filed February 29, 1904. Serial No. 195,831, (No model.)

To (07/ [Pi/1H1) it Dt/t concern:

Be it known that we, Janus M [TC/HELL BAW- DEN, residing at Seymour street, and EDWARD HEXEY GATTERALL, residing at Breed street, in the township of l.raralgon, county of Buln Buln, State of Victoria, Commonwealth of Australia, subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements in Double-Legged Coupling-Pins for Road-Vehicle Shafts, of which the following is a specification.

The object of our invention is to provide a cheap, simple, and effective double legged pin and holdfast for pivoting the rear ends of road-vehicle shafts to the forks or front axlebar or extension therefrom. In the past various devices have been used to this end; but with our invention no alteration is called for either on the shaft end or the fork. Our pin can be applied to old as well as to new vehicles, is reversible, can be either attached or detached in a few seconds and calls for no tools in so doing, and has no threaded portion to become stripped or corroded and no nut to work off and become lost. Accidents are thereby prevented and the convenience and safety of those concerned increased.

Referring to the drawings, which form a part of this specification, Figure I shows an end view of our double-legged pin looking at it in the direction of the arrow shown in Fig. 2. Fig. 2 represents a side elevation of our double legged pin removed from the fork-legs and shaft end. Fig. 3 depicts a view of our double-legged pin in place looking at it from the vehicle side. Fig. 4 represents a plan of Fig. 3.

Similar letters of reference indicate similar or corresponding parts where they occur in the several views.

()n reference to the drawings it will be seen that A is the upper leg or pin, and A the lower. Uniting these two legs is the bend B. The legs and bend are all of one piece of material, which is round in section and may be of wrought-iron or steel and forms an approximately U shaped coupling. Through the outer end of the upper leg is formed a hole, hereinafter called the pivot-pin hole, to accommodate a pivot-pin C. The ends of this pin overhang the leg, and to it are pivoted the wings D, forming the upper portion of a holdfast or closure E. which extends downwardly past the lower leg, and in it is made a hole F, whose diameter is larger than the diameter of the lower leg. so that'the lower end of'the holdfast (which can travel through ninety degrees) passes easily over the outer end of the lower leg. Through the lower leg is formed an inclined hole. hereinafter called the splitpin hole, to accommodate a split pin G. This hole is inclined to facilitate the application or removalof the said split pin.

On reference to Fig. 3 it will be seen that B is the bend of the pin. One of the forklegs is marked H, and the shaft end is marked J. The lower leg A may also have a pivotpin hole K formed therein in addition to the split-pin hole, and the upper leg A may have a split-pin hole K. Thus the holdfast and split pin may be attached to either leg A or A.

As before described, either the top or the bottom leg may pass through the forks and the shaft end and be used as a coupling-pin.

'e do not restrict ourselves to the precise form or dimensions of parts shown in the drawings, as the parts can be changed in form while substantially embodying all the essential features of the invention.

To apply our invention, the split pin G is removed from the lower leg and the lower end of the holdfast swung off the end of the lower leg and elevated through ninety degrees. The said lower leg is then pushed through the hole in the outer fork-leg, through the hole in the shaft end, and through the hole in the inner fork-leg. The lower end of the holdfast is then swung back over the outer end of the lower leg. The split pin ("i is then inserted in its hole and the shaft end is securely locked between the fork-legs.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. An improved double-legged coupling-pin for road-vehicle shafts consisting of an upper leg and a lower leg united by a bend, said upper leg having a pivot-pin hole therein, a

pivot-pin in the said hole having overhanging ends, a sheet-metal holdfast having wings on its upper end pivoted to said pin, an opening in the lower part of said enlargement to accommodate the end of the lower member, a hole in said lower leg, and a split pin in said hole, all substantially as and for the purpose described.

2. An improved double-legged coupling-pin for road-vehicle shafts consisting of an upper leg and a lower leg united by a bend, said legs being ofthe same length and each having therein a split-pin hole and a pivot-pin hole, in combination with a pivot-pin in the upper leg, a sheet-metal holdfast, wings above said 5 In witness whereof we have hereunto set our 20 hands to this specification in the presence of two witnesses.
